Base on the successful experience of US-8001D, the RU-8011D is designed with JTS 2nd generation wireless technology. To cope with the squeezed radio spectrum, the system provides more compatible channels within limited bandwidth. The patent pending REMOSET sends the scanned channel data to transmitter by pushing a button. To meet critical audio demand general noise and hiss noise have been reduced to an extremely low level. 100 meter operation range meets most demand from most applications. To be environment friendly an integrated charger is available on option.
